A first application is about fifteen lines

Point a fetch at your own host and read the tool catalog back:

const res = await fetch("https://<your-host>/mcp", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    Authorization: `Bearer ${token}`,
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "tools/list",
  }),
});

const { result } = await res.json();
console.log(result.tools.map((t) => t.name));

Swap tools/list for tools/call with {"name": "aida_list_projects", "arguments": {}} and you have your matters.
